Rosie O'Donnell is "happy to be alive" after suffering a heart attack last week.
"I am lucky to be here," she wrote on her blog Monday.
O'Donnell, 50, wrote that she began experiencing symptoms, such as sore arms and an ache in her chest, on Tuesday after helping "an enormous woman/struggling to get out of her car."
After a Google search suggested she was having a heart attack, O'Donnell said she took Bayer Aspirin, but did not call 911.
The next day, she said her doctor informed her that her "LAD was 99% blocked."
"Know the symptoms ladies/listen to the voice inside/the one we all so easily ignore," she wrote.
